Verdict

Operating-company assertion

This verdict is based on the fact that ZUGARA Inc., an operating company engaged in developing and commercializing augmented reality software, is the current assignee of the patent and has been involved in litigation since at least 2025 (case 2:25-cv-00437). All recorded assignments are internal transfers of inventor rights to ZUGARA Inc., with no evidence of transfer to any shell entity or known NPE. The recurrence of Matthew T. Szymczyk, an inventor and CEO of Zugara Inc., as the correspondent for all assignments further supports that these were internal company actions (Reel 047951/0611, 065600/0868, 065012/0186, 047809/0177, 047951/0591).
